Fullpage.js disable vertical scroll on section

问题

I require one section to be "hidden". As i have links that "silentMove" to the slides in the section.

I have tried to use the following with no luck data anchor is "investments":

afterLoad: function(anchorLink, index){
if(index == 4 && slideAnchor == 'investments'){
$('body.fp-section.investments').find('.fp-slide').index(4,0);
    $.fn.fullpage.setAllowScrolling(false, 'down'); 
    $.fn.fullpage.setKeyboardScrolling(false, 'down');
}
},

Only solution i could come up with was:

    afterLoad: function(anchorLink, index){
    if(index == 4 && anchorLink == 'investment'){
    $('body.fp-viewing-investment').find('.fp-section').index();
        $.fn.fullpage.setAllowScrolling(false, 'down'); 
        $.fn.fullpage.setKeyboardScrolling(false, 'down');
    }
  if(index == 3 && anchorLink == 'section3'){
    $('body.fp-viewing-section3').find('.fp-section').index();
        $.fn.fullpage.setAllowScrolling(true, 'down'); 
        $.fn.fullpage.setKeyboardScrolling(true, 'down');
    }

This is a shorter code, but you can not leave section 5, once you enter with silent move to:

    afterLoad: function(anchorLink, index){
    document.body.style.overflow = "hidden";
  document.body.className += " no-scroll";}
